Data retrieval is easier with the getKey(), openKeyCursor() and
continuePrimaryKey() methods.

And bulk recovery of entire datasets no longer needs a cursor with the
getAll() and getAllKey().

Full screen Progressive Web Apps

When Progressive Web Apps are launched from the Android home screen, they
launch in a standalone app-like mode that hides the omnibox. This helps
create an engaging user experience, and frees up screen space for content.

However, for even more immersive experiences like games, video players,
or other rich content, mobile UI elements such as the system bars can
still be a distraction and take up valuable pixels that you may want.

Now you can make your Progressive Web App feel fully immersive by setting
display: fullscreen in your
web app manifest.

in standalone mode (middle), and launched from the home screen in
fullscreen mode (right).

When your app is launched from the home screen, all non-app mobile UI
elements will be hidden.

Sandboxed iframe Improvements

When triggered by a user interaction, this keyword gives sandboxed iframes the
ability to navigate the top-level page, while still blocking auto-redirects.

And more!

And of course, there’s plenty more.

Say goodbye to the clearfix hack. Instead of manually resetting
multiple layout properties like float and clear, you can now add a new
block-formatting context using display: flow-root.

PointerEvents.getCoalescedEvents() allows you to access all input events
since the last time a PointerEvent was delivered. Perfect for when you
need a precise history of points for things like drawing apps.

And Workers and SharedWorkers can now be created using data: URLs,
making development with Workers more secure by giving them an opaque origin.

These are just a few of the changes in Chrome 58 for developers.
